| 摘 要： | 针对各种岩溶发育地带的地球物理特征,构建相应的地电模型,采用时域有限差分法作地质雷达正演模拟。根据电磁波在介质中的传播规律,分析各种岩溶模型情况下所得正演剖面结果的振幅特性,相位特性,频率特性。总结岩溶探测过程中各种构造的地质雷达响应,作为实际工程探测的依据。从而,验证了利用时域有限差分方法作地质雷达正演模拟的可行性,也有助于实际勘探岩溶塌陷灾害隐患的定性到定量的分析。

| Abstract: | Ground penetrating radar forward modeling was carried out by the method of FDTD.According to the terrestrial physical characteristic of karst areas,the corresponding terrestrial electricity models were structured.On the basis of the law of the electromagnetic traveling in medium,the amplitude characteristic,phase characteristic and frequency characteristic of the simulation results were summed up.The ground penetrating radar responses of various structures were studied and some conclusions which were of gre... |
